“…Nanostructured materials synthesis and maintaining their physical properties like mechanical rigidity, thermal stability or chemical inactivity is a challenge to the scientific community. Different physical and chemical methods like hydrothermal, sol gel, impregation, precipitation, solid state dispersion, reflux, coassembly, chemical reduction, thermal irradiation, and microemulsion have been employed for the synthesis of different dimensional inorganic and organic nanostructured materials [12][13][14][15][16]. Amongst these, µ-emulsion is one of the best method to synthesize nanostructured materials of different size and shape because of its cost effectiveness, environmentally friendly adaptable preparation method which control the size, geometry, morphology, homogeneity and surface area of the nanoparticles [17][18][19].…”

The nanostructured materials are the basic scientific interest in the research community. The properties of nanostructured materials with their variable sizes, shapes and reduced dimensions boost their performance towards wide variety of applications concomitant to electronics, optoelectronics, sensors, photocatalysis, and biomedical field. Among all the established methods to design nano structured materials, micro-emulsion has attained a significant role because of its unique properties like thermodynamically stability, ultralow interfacial tension, and large interfacial area. Apart from its versatility, microemulsion is one of the most cost effective and environmentally benign preparation method which can control the particle size, geometry, morphology, homogeneity, and surface area of nano structured materials. This review article focuses on the recent development in the above area, various factors that influence the oilin water micro-emulsion (µ-emulsion) to formulate different shapes and size of nano structured materials.

“…Recently, magnetic nanoparticles have attracted significant interest in a wide range of applications, such as cell separation, enzyme immobilization, and targeted drug administration [8,9,10]. Magnetic nanoparticles commonly contain elements such as iron, nickel, cobalt, and their alloys or oxides of magnetic elements [11,12,13,14]. The preparation of magnetic nanoparticles mainly involves chemical methods, including pyrolysis, co-precipitation, sol-gel, micro emulsion, ultrasonic chemistry, electrochemical deposition, and laser decomposition [15,16,17,18].…”

Lysozyme is in high demand due to its many favorable characteristics such as being naturally occurring, non-toxic, and easy to digest and absorb. Recently, superparamagnetic nanoparticles with strong magnetic responsiveness have attracted significant interest for enzyme purification. The aptamer of the enzyme can be chemically synthesized rapidly at a large scale using simple and low-cost preparation methods. Therefore, Fe3O4 nanoparticles (Fe3O4 NPs) were prepared by chemical co-precipitation and were then functionalized with amino groups to produce NH2-Fe3O4 NPs. The specific reaction of aldehyde and amino groups was used to attach lysozyme aptamers with specific sequences to NH2-Fe3O4 NPs to produce Apt-NH2-Fe3O4 NPs. The synthesized materials were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), hysteresis loop analysis, and thermogravimetric analysis (TGA). The optimal experimental conditions for adsorption of lysozyme were investigated. The effects of initial lysozyme concentration, adsorption time, pH, reaction temperature, and ionic strength were determined. The maximum adsorption capacity and relevant activity of Apt-NH2-Fe3O4 NPs was 460 mg·g−1 and 16,412 ± 55 U·mg−1 in an aqueous lysozyme solution. In addition, as demonstrated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) electrophoresis analysis, lysozyme could be separated from crude fresh egg white using Apt-NH2-Fe3O4 NPs with an amount up to 113 ± 4.2 mg·g−1 and an activity up to 16,370 46 U·mg−1.

“…Ferrite is a new composite oxide composed of iron and one or more other metals, which can be a ferromagnetic metal oxide. [11][12][13][14] According to its lattice type, ferrite can be divided into spinel ferrite, lead ferrite and garnet ferrite. Among them, spinel ferrite, as a new type of semiconductor compound, has the characteristics of narrow band gap, response to visible light, stable photoelectrochemical performance, high reusability, and good photosensitivity and stability.…”
